نقل قول:
نه بلندی صدای این مدل از X5 و O2 و D2+ و D2 و حتی i7 هم کمتره.
به نظر میاد کمی صدای D3 گرم تر و متوازنتر از J3 هست توجه داشته باشید اگه این پلیر رو تهیه کردید حتما آپدیتش کنید! و به خاطر داشته باشید که فقط پلیر مهم نیست شما اگه همون پلیر قبلی خودتون رو نگه دارید و هزینه برای هدفون بکنید و کیفیت آرشیو آهنگهاتون رو افزایش بدید تغییری که حس خواهید کرد به مراتب بیشتر خواهد بود.
من توی اینترنت خیلی سرچ کردم ... هیج یوزر حرفه ایی این تفاوت رو تایید نکرده .
این هم از نتیجه تست ادمین سایت iAudiophile.net
This tired old placebo topic seems to crop up with every new player being released, just the people claiming to hear "huge differences" are changing...
The J3 and D3 sound exactly the same - which also is exactly the same as any other modern Cowon (or any other non-broken player, for that matter). People claiming they hear a difference are talking complete nonsense. Or maybe they indeed have a broken player - or don't know how to volume-match two players for a honest AB comparison.
I did a lengthy volume-matched AB test between the D3 and J3 (both matched to within 0.5dB SPL), with both dynamic driver (Sennheiser IE8) and multi-armature (Earsonics SM3) IEMs, and there is not even the tiniest noticeable difference to be heard. Besides flat output I also tested various BBE settings on both players, and they also sound exactly the same.
I wish this spreading of lies and placebo preconceptions about differences in sound quality where there are none would stop. But some people like to believe in fairy tales, it seems.
